A sustainable energy economy requires the development of new, high-efficiency, energy-conversion/storage technologies. This is where lithium batteries and supercapacitors come in. Research into these electrochemical systems is mainly devoted to implementing the specific power of batteries and the specific energy of supercapacitors, with safety as primary issue. Much attention has been devoted to the use of ionic liquids (ILs)-based electrolytes for their intrinsically higher safety than the conventional carbonate–based ones. Indeed, the ILs feature very low vapour pressure, low flammability, high chemical, thermal and electrochemical stability, and good conductivity particularly above room temperature. Here, recent studies on the development of IL-based supercapacitors and batteries at the LEME (Laboratory of Electrochemistry of Materials for Energetics) group of the University of Bologna will be presented and discussed. The lecture will focus on different configurations of IL-based supercapacitors and on the cutting-edge Li/O2 batteries operating with IL-based electrolytes
